Our Team

Shannon Ostransky - Registered Dental Hygienist

When you come to Nye Avenue Dental you'll know Shannon right away because her contagious laugh can be heard throughout the office!  You will appreciate the way she takes her time getting to know you personally, and your mouth.  She listens, educates, and encourages everyone she meets.  She is excellent at what she does!  She has been a dental hygienist for 20 years, 8 of them with Nye Avenue Dental.  She also served as the president for the Lincoln Dental Hygiene Association for 4 years.  

Originally from Potter, NE, Shannon now lives in Fremont with her husband Mark Ostransky and their 2 children.  If you need a car wash, large event tent, or home repair or remodel, Mark is the one to call!  They stay busy with their three businesses: Hurricane Mike's, the tent division of Rodgers Tent and Awning, and Mark of Excellence. 

When she's not in the office filling the walls with laughter, you will find Shannon with her family.  It may be volunteering at her kid's school, gardening, reading, traveling, being outside, enjoying sports or participating in a half marathon. 

Sara Kellogg - Registered Dental Hygienist

Truth be told, Sara and Dr. Bethany Olson have known one another since elementary school right here in Fremont!  You will appreciate Sara's gentle touch and spirit when she cleans your teeth.  Her attention to detail will impress you from the first time you see her.  She has been a dental hygienist for 19 years, 10 of them at Nye Avenue Dental.  

The Fremont Community is blessed to have Sara and her family in town.  Their committment to Fremont is here to stay.  She and her family are also sports enthusiasts!  In addition to watching their own children compete every season, from football, to soccer, to volleyball to wrestling, she and her husband Will have also closely followed her Dad and brother's coaching careers in Fremont, Wahoo, and Gretna.  

When Sara has free time away from work, you will find her serving Bergan and St. Pat's church, hosting friends with hospitalitiy, and loving time with her family!

Ashley Tosaya - Registered Dental Hygienist

Ashley grew up near in Broken Bow, NE and a fun fact about Ashely is that she attended one room country school up until 8th grade!  There is actually a NET TV special where her and her previous school are highlighted as one of the last of it's kind!  She and Dr. Olson were in school at UNMC College of Dentisty together and met through the Christian Medical/Dental Association while in school.  

Ashley joined Nye Avenue Dental two years ago, when her husband Jeremy's job of a collegiate soccer coach moved them back closer to her family.  They are always finding the next fun way to entertain their 3 year old son, from monster truck shows, to pumpkin patches! 

Ashley enjoys, fitness, traveling, time with family, and of course watching soccer games!

Deb Siffring - Scheduling Coordinator 

Deb is the face everyone sees first at Nye Avenue Dental! She is the warm smile at the front door, greeting you and remembering to ask about your most recent family vacation, graduation, grandchildren or other major life milestone.  She remembers because she genuinely cares about the people we serve and their personal stories.  She is the voice of concern over the phone and the one to remind you that you need another dental appointment.  She is good at keeping us all on track!  Deb has been in the dental profession for over 30 years, nearly all of them with Nye Avenue Dental!  

She wears many hats, as she and her husband, Jim own Siffring Landscaping here in Fremont as well.  They do a fabulous job of beautifying Fremont with their plants and landscaping expertise.  It has been fun to see their business grow into two locations in the last few years and to be helping with Christmas decor in the winter months as well. Together, they have 3 children, and now 4 grandchildren! 

Deb finds time with family a priority.  She travels to St. Louis and Kansas City to stay active in her grandchildren's lives, making sure to be at every Christmas program and birthday party.  She has the natural ability to draw people together and will make you feel like a lifetime friend the moment you meet her.

Earlene Bedsole - Certified Dental Assistant 

Earlene started her dental assisting at Nye Avenue Dental as an intern while she was still in dental assisting school.  She impressed us so much with her work ethic and knowledge that we never let her leave.  Immediately after her graduation, she began working with us.  That was 9 years ago, and we have been thankful for her ever since.  She recieved her official certification in 2016 after completing the difficult Dental Assisting National Board Exam.

Earlene is orginally from California, but now calls Fremont home and has for the last 18 years.  Meeting her husband Chris, who is a native of Fremont, was a good reason to stay!  Her four children always keep her running, and she wouldn't have it any other way.  

Earlene enjoys cooking, and is always ready to share a good recipe.  She is artistically talented and decorated our annual pumpkin last year that glows in the dark!  

Tiffany Siffring - Dental Assistant

Tiffany has been a cherished employee at Nye Avenue Dental for 26 years.  She is most definitely a top notch dental assistant, but her true title should be more along the lines of "master of all trades."  She is able to fill any role in the dental office, with confidence, a genuine smile and ease.  Tiffany is a quick learner and natural leader.  We all turn to her when there is a problem that needs to be solved, dental or otherwise!  

Tiffany lives in Arlington with her husband Jeremy.  They are finding themselves on the road more, as they sent their youngest to college this year.  It's now a town or state away to visit one of their 2 children.  You will also see them both working at the family business, Siffring Landscaping.

Tiffany is a natural leader when it comes to a good conversation.  She is quick to listen and always has a caring or sarcastic comment to lighten the mood.  She loves a good book, yoga, and a great workout.
